산업단지내 위험물 저장탱크 기초의 결함으로 인한 위험물질의 유출사고는 인근 지역의 대형 인명사고 및 대형화재를 야기 시킬 수 있으므로 기초의 설계 및 시공단계에서 세심한 주의를 기울여야 한다. 본 연구에서는 위험물 저장탱크 기초의 안정성 평가를 위하여, 대표적인 탱크 기초 유형을 네 가지로 분류하고 각 유형에 대한 3차원 유한요소해석을 수행하였으며, 수치해석 결과로 나타난 탱크기초의 응력 및 침하량 크기와 분포 특성을 비교 평가함으로써 각 기초 유형별로 위험물 저장탱크의 설계 및 시공 가이드라인을 제시하였다. Because leakage incidents due to the defect of hazmat tank foundations in the industry cluster area can cause the tremendous fire and human disaster, the proper design and construction of tank foundation is required to prevent the tank leakage. In this study, four types of typical tank foundations were classified and modeled for3D FEM analysis to provide their stability evaluation. The appropriate guidelines for the design and construction of tank foundations were suggested through the assessment of the numerical analysis results on the stress distribution and displacement of the tank foundations.

Currently, high-risk business sites that handle accident-preparatory materials more than the designated quantity must submit a risk management plan. Through this, the company manages the risk of spreading out of business sites due to chemical handling. However, as the number of chemical businesses in Korea increases day by day, the frequency of accidents and their damage are only increasing. At this time, initial response is important to reduce accident damage, but in small and medium-sized businesses, initial response is not good. To solve this problem, the emergency response information sharing system in the project site management plan should be established to jointly respond to accidents. In this study, we derived information that can be shared in establishing a system for sharing emergency response information among businesses. It also provided guidelines for improving emergency response information and establishing a system for sharing emergency response information among businesses.

The analysis of causes for the chemical accidents, in National 119 Rescue Headquarters(NRHQ) had the highest percentage of acids (e.g. HCl, HNO3, H2SO4, HF, etc) in five years. One of the ways to response to acidic accident, neutralization, is a method of removing and treating hazardous substances by converting acidic chemicals into salt and water with low cost and effort. However, due to the instantaneous heat generated during the quenching process of the acid & base neutralizer of the liquid-state accident material, harmful gas is diffused into the atmosphere, which can not guarantee the safety of the neighborhood as well as the safety of the firefighter. In this study, the hazards of calcium hydroxide(Ca(OH)2) and sodium hydroxide(NaOH), which are used as base neutralizers, were identified by replay experiments. The result of excellent neutralization of acidic chemicals (e.g. neutralization, economics, health risk, effectiveness) of the new base neutralizing agent “sodium bicarbonate(NaHCO3)” was obtained.

In this study, fire defense science classes centered on science were trained for scientific laboratory practitioners and science teachers at elementary, junior high and high schools, and the recognition and investigation were conducted on the educational effects of the fire defense science classes, the possibility of practical use in actual education sites, the necessity for fire defense safety and science cooperation, and the necessity for introduction into the current curriculum. As part of various programs for youth fire defense safety, the basic data for the nationwide expansion of fire defense science classes were obtained. According to the survey, 95% of the respondents said that fire science classes could be used in schools, while 98% said that education would be effective. In addition, 99% of the respondents said the subject of the fire defense science class was appropriate for safety and scientific cooperation, while 94% said the current curriculum needed to be introduced.

The purpose of this study was to determine the difference rate of the results for classification of chemicals by the criteria of GHS between Korea and Japan. A total of 200 chemicals with same Chemical Abstractive Service (CAS) number in Korea and Japan were finally selected for comparison. In order to determine the difference rate of for classification of chemicals, we compared the results in 15 classes (13 classes for health hazard and 2 classes for environmental hazard). Moreover, we analyzed the causes for leading to the different outcomes. The overall matching rate was 55.7%. The lowest matching rates were observed in ‘single exposure (27.5%)’ and ‘repeat exposure (37.0%)’ categories among the ‘specific target organ toxicity’ hazard class. Similarly, the highest matching rates were found in “Respiratory sensitization” and “Aspiration hazard” (94.0%, 91.0% for each). This study indicates that outcomes classified and labeled by GHS among countries could be different because they have performed the classification of chemicals by their own standards and interpretation of GHS. To minimize these differences, it is necessary to establish the technical guideline including the standardization for criteria of GHS internationally, the standardization of process in determination by experts, and provision of same reference list to be used, through an international or multi-party GHS expert committee.
